"T all whom-it may concern: *Be---it-known' that I, ALMER NEWTON BLAZER, a citizen of the United States, and a resident-of :Mescalero, in the county of -"-Otero and State of New/Mexico, have in- ;Ventedcertain new and usefullmprovements in Pressure Generators, ofswhich the following is a; specification.

My invention-is an improvement inpressure generators, wherein the original elements as; for-instance, airyfuel and water are brought to the-generator under a a sur- 4 "plus pressure, and; has for its obje'ct to proride a generator of the character specified f or -z;developing a continuous-fpressure, of fluid, as; for instance,-g-as, steam, combined gas and steam gases of combustion and water -or other combinations; for; any purpose, asgffor instance, operating an engine, .0 with o provisions for maintaining the initial pressurejof the severalexpansive elements F in separatechambers for each. "element.

A further object of the invention :is, to bring the air and fuel separately from their ,2 respective schambersto a combustion chamberand mixingsthem in combtustibleproportio'ns andiigniting ithe mixture.

A further; Iobj ect of the invention is e to 1 introduce theHwaterQ-in such amount-that/the heat of combustion will evaporate the same under required pressure and t in ,uniting the gases of combustion with thensteampro-i duced, i delivering ithe combined Volume un- 1 den pressure to "the engine.

The water and fuelare supplied/ -to their --,resp.ective chambers by reciprocating pumps 5 and 6 ofnsual construction,,-each pump havinga piston rod 7' which extends toward the engine 8, andis provided -with a roller i 9 {at ;the end remote from-; the pump-for J engagement by a;cam 10 on a cam shaft 11 which; is journaled transversely of the bed 313121136 '12 between the engine and thecasing. This bed late 12supports the generator :and is nig'id ly connected witlrjthe engine. The,;plungers of the pumps are moved in none? directionqby thecam and in the other direction :by coil; springs 13 which encircle :the rods between ,steps 14 on} the rods and athe ibarrels; of the} p tunps. 'Lhe; fuel, flows from'the p ump 5 throu'gh a pipe 15 to -the chamber adjacent to the; diaphrag;m i 3 and wh nc throug a Perm-fie b lat id q i to: a valve 26 to be; also; described, and the aw rpas e iromthe puma l by; Way a :pipe 516, to;- the central-f chamber, from which it i has access I directly to the alve 25, 1 to be described, thr ugh op i gs in at ul ing 28.

" as shown in Figure 1.

The flow of the water, fuel and air from the respective chambers to the combustion chamber is controlled by three needle valves 25, 26 and 27, respectively, which are arranged in tubular casings 28 extending through the central chamber 1 at the center thereof. Each of these tubular casings has a nozzle 29, 30 and 31, respectively, which delivers to the combustion chamber 24:.

Referring to Figure 5, it will be seen that the nozzle 31 curves upward toward its free end, delivering at the outlet of the nozzle 30 and that the nozzle 29 delivers behind a bafiie plate or jacket 32 which separates the water from the fuel and air mixture during combustion of the fuel.

It will be noted, referring to Figure 6, that the port or passage leads laterally inward from the chamber at the diaphragm 4, and this port or passage 50 opens into the casing 28 which contains valve 27, the said valve controlling the flow of air. 7 A port or passage 52 leads inwardly from the chamber adjacent to the diaphragm 3 at that end of the casing remote from the air chamber, the

passage 50 being at the end adjacent to the air chamber, and thence forwardly to deliver to the passage 28 containing the valve 27. These ports 50 and 52 are placed at the ends of the housing 1, in order that they may not interfere with the flexibility of the diaphragm.

Any suitable igniting device may be arranged to ignite the mixture of fuel and air. E'achcof the needle valves passes through a stufling box 33 at the outer end of the tubular casing 28 in which it is arranged,

and a worm wheel 34is secured to each valve outside of the casing. These worm wheels are engaged by worms 35 on a commonshaft 36 which is journaled in a bracket 37 held at the rear of the casing by plates 38 secured to the casing and engaging the top and bottom of the bracket.

The worm wheels are held on tapering portions of the valves by lock nuts 39, and it will be obvious that by means ofthe shaft the valves may be simultaneously adjusted. It will be seen that the adjustment of the shaft 36 will result in the simultaneous r0- tation of the members 25, 26 and 27 so that the supply of water, fuel and air is simul taneously regulated. Of course, any suitable means may be employed forfturning the shaft 36.

Attention is directed to Figure 5 wherein it is illustrated that the members 25, 26 and 27 have threaded engagement with the intermediate portions of the tubular casings 28 as indicated at 189 so that when the valves 25, 26 and 27 are rotated they will 34 will t all times be in engagement with the operating shaft.

In operation, the initial pressure s determined by the pressure of the air inthe chamber adjacent to the diaphragm 4E and controlled in any suitable manner. The central and the other lateral chamber are filled to capacity with water and fuel, and the three elements, through the flexing of the diaphragm, are brought under equal pressure and so maintained to the extent limited by the flexibility of the diaphragm.-

Air flows through the nozzle 31, and is mixed with the fuel flowing through the nozzle 30. This combustible gas is fired'by any suitable firing means, and continues to burn as the air and fuel flow. The bafile plate 32 and the tube 24 are heated and the water flowing in over the bafflaplate 1s vaporized, forming steam which s united with the burning gases and is delivered to the engine. I claim: I
